United States atet 3,011,277 HIGHWAY SLOPE FINISHING MACHINE Oscar Lee Arnold, Jasper, Ala. (1309 E. Broad St., East Gadsden, Ala.) Filed Oct. 29, 1958, Ser. No. 770,384 1 Claim. (Cl. 37-145) This invention relates to a highway slope finishing machine. It has for its main objects to provide such a machine that will be highly satisfactory for the purpose intended, simple in structure, comparatively cheap to manufacture, easy to use and keep in working condition, and very durable.

In the building of highways at the present time there is no machine in use intended for cutting the slopes where a highway passes through hills with the result that other kinds of road building machines are used which are not entirely satisfactory for the purpose and increase the cost of forming the slopes. The present machine is intended for cutting the slopes in an easy and satisfactory,

manner without loss of time and additional expense.

Other objects and advantages will appear from the drawings and description.

By referring generally to the drawings it will be ob-" served that FIG. 1 is a perspective view. of a machine made according to this invention adapted for attachment to a tractor or the like for use; FIG. 2 is a side elevational view showing the cutter and motor attached thereto; FIG. 3 is a detail side view of the cutter and motor; FIG. 4 is a bottom plan view of the machine; FIG. 5 is a de-' tail side view showing how the cutter is'operated; FIG- 6 is a top view of FIG. 5; FIG. 7 is an enlarged detail view showing the cutter blades and bearings; FIG. 8 is an enlarged detail view of the cutter blades and supports; FIG. 9 is an endsectional view showing mechanism for raising and lowering of screed; FIG. 10 is a side elevational view of FIG. 9; and FIG. 11 is an end view of the machine showing the screed and cutter.

Similar reference numerals refer to similar parts throughout the several views.

First of all it should be'observed that the present invention is a structure that forms an attachment for use in combination with another kind of unit for. highway building, and having as part thereof power means. Such a unit is no part. of the present invention which comprises a structure for the purpose of removing earth to form a sloping condition at the side of a highway being made through a hill. As part of its structure it is provided with a motor mounted at a suitable place vfor operating 'ice 12 supported in bearings. A stud bolt '13 is attached in the outer edge portion of the wheel. A connecting rod 14 is attached by an end thereof to the stud bolt with its other end 15 attached to a bar 16 supported in rollers 17. A plurality of cutters 18 are supported slidably in the main slope arm member 19 which is hinged at 20 to to frame having the flat top. The slope member is supported at its outer end 21 by a cable 22 control means (not shown) on the motor patrol (not shown). The screed is provided with adjusting means 23.

c From the foregoing it will appear that the machine is adapted for removable attachment by any suitable means to the side of a tractor, motor grader, or any otherk-ind of highway building machine that will enable the slope machineto make contact Wtih its cutters to thus remove earth to provide a slope at the side of a highway.

The various parts ofthe machine may be made of any material suitable for the purpose, but I prefer to use good grades of metal; also the machine may be made in different sizes and capacities depending on how. and where to be used. The internal combustion motor for operating the cutters would be of sufiicient horsepower to drive the cutter mechanism.

While I have shown and described the preferred embodiment of my invention, I do not wish to limit same to the exact and precise details of structure, and reserve the right to make all modifications and changes so long as they remain within the scope of the invention and the following claim.

Having described my invention I claim:

A highway slope finishing machine adapted to be attached to and moved by a highway building tractor, said machine comprising a main arm structure having a front and a'rear side, hinge means on one end of said structure adapted to removably attach said structure to said tractor, cable means on the other end of said structure adapted to support said other end on the tractor, adjustable elongated screed means on the rear side of said structure, a flat portion on said one end of said structure adjacent said hinge means, an internal combustion engine mounted on said flat portion,

a bar means mounted on the front side of said structure .for reciprocating movement relative thereto, a plurality 'bar means in driving relation whereby said cutters are longitudinally reciprocated relative to said structure to V scarify earth prior to sloping by said screed means as the earth cutters. It has no means for self moving and p v for this reason it is attached to the side of a tractor, mo

tor grader or the like. Means for such attachment are plainly shown in the drawings. 1

Referring to the drawings in detail it will be seen that the structure is attached by arms 1 that are connected to a turn table 2 and a blade 3 ofa motor patrolor grader. A frame 4 provided with'a flat top 5 is supported by arms 6 attached by their ends to rod arms 7. A. gasothe slope finishing machine is moved forwardly.
